ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 2

Short Range (radio or radiocommunication) Devices (SRDs) as per Report ITU-R SM.2153-4 referred to in Rec. ITU-R SM.1896

For the purpose of this Report the term SRD is intended to cover radio transmitters which provide either unidirectional or bidirectional communication and which have low capability of causing interference to other radio equipment

Such devices are permitted to operate on a non-interference and non-protected basis .

SRDs use either integral, dedicated or external antennas and all types of modulation and channel pattern can be permitted subject to relevant standards or national regulations

Simple licensing requirements may be applied , e.g. general licences or general frequency assignments or even licence exemption, however, information about the regulatory requirements for placing shortrange radiocom. equipment on the market and for their use should be obtained by contacting individual national administrations

as per Report ITU-R SM.2255
RFID: Radio-Frequency Identification
RFID tag: any transponder plus the information storage mechanism attached to the object
RFID system:
 an automatic identification and data capture system comprising one or more RFID reader (interrogators) and one or more RFID tags
(transponders) in which data transfer is achieved by means of suitably modulated inductive or radiating electromagnetic energy.

A tag is attached to the item to be identified, and a transmitter/receiver unit interrogates the tag and receives identification data back from the tag.
RFID devices are considered: active if self-powered – i.e. contain their own batteries and are always on, and passive if receive power from an external source – i.e. radio frequencies transmitted by readers
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 4

as per Recommendation ITU-R SM.1755:
Ultra-wideband technology (UWB):

Technology for short-range radiocommunication, involving the intentional generation and transmission of radio-frequency energy that spreads over a very large frequency range, which may overlap several frequency bands allocated to radiocommunication services

Devices using UWB technology typically have intentional radiation from the antenna with either a –10 dB bandwidth of at least 500 MHz or a –10 dB fractional bandwidth greater than 0.2
(see calculation formulae in Rec. ITU-R SM.1755)
Notes: Administrations authorizing/licensing use of UWB devices:
- should ensure this use on a non-interference/non-protection basis with respect to radiocommunication services (RS) operating in accordance with provisions of the Radio Regulations;
- should take immediate action(s) to eliminate interference to RS
5 ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva

Definition as per No. 1.15
of Radio Regulations (RR):
Industrial, Scientific and Medical (
) applications (of radio energy)
Operation of equipment or appliances designed to generate and use locally radio frequency energy for industrial, scientific, medical, domestic or similar purposes, excluding applications in the field of telecommunications.
Bands designated for ISM are listed in RR Nos. 5.138
and 5.150
as well as in No. 5.280
for some European countries
RR No. 15.13
: mandatory provisions to ADMS to ensure that radiation from ISM equipment is minimal in ISM bands and is at a level that does not cause harmful interference outside ISM bands to a radiocommunication service and, in particular, to a radionavigation or any other safety service operating in accordance with RR provisions.
(Similar provisions as above for “outside ISM bands exist in RR No. 15.12 for electrical apparatus or installations of any kind)
(Administrations should be guided by the latest relevant ITU-R Recommendations)

(2011): Impact of emissions from
SRDs on radiocommunication services (RS)
- Different approaches can ensure RS protection from SRDs: define
SRD emission masks and exclusion, restricted or harmonized bands;
- Noting that SRDs are certified and regulated at the national level;
- further developments and studies can be carried within ITU-R and lead to new/revised Rec. & Rep. providing guidance to administrations
